, a life sciences company dedicated to accelerating patient access to evidence-based innovation in mental health, has received approval from the FDA for a clinical trial in psilocybin therapy for treatment-resistant depression. Regulatory approvals for the trial have already been given in the UK, the Netherlands and Canada.

The trial is a phase IIb dose-ranging study with 216 patients taking part in 12 to 15 research sites across Europe and North America. It will begin in the UK later this month and sites in other countries will join the trial as further regulatory approvals are received.
